ATLAS tasks read information from databases while they are running, and one of these databases at CERN is being upgraded on 7 April and hence will be down for up to 8 hours (working hours in Europe). However there are replicas of this database in France in Canada and tasks should be able to fallback automatically to using those when the CERN database is down. So in theory there should be no disruption however access to the fallback databases may be slower due to the heavier load. |
